Crackling sound with digital out

post #1 of 7
Thread Starter 
I just connected my ONKYO HT-SR700S to my media center via an optical out cable. I have an ASUS P5AWD-E Premium board with onboard sound. I am running MCE 2005. I have noticed that when I move through the menus on MCE, I seem to get a loud cracking/spitting noise out of the system. At the same time this occurs, I notice the digital signal thats displayed on the onkyo reciever dissapears for a second. Any ideas, why this would happen? Other than this issue the sound system works fine.

Thanks in advance for any comments

might be the sound card drivers suck

I use coaxial out of my Asus board and don't have problems like that. It could be any number of issues, I would start by using a coax cable. That should tell you if it's a cable problem or a configuration problem.

Ive had that problem before, I cleaned the fiber optic part of the cable and all was better. Hope that helps.

Is this onboard ADI Soundmax? The Asus drivers for these are (as bulls points out) erm bull.

I originally gave up on my P5 board's onboard audio under XP although oddly enough it was always OK under Vista. However a few weeks ago I decided to have another try as I wanted to use the optical (TOSLINK) port for something.

Anyway, after some rigerous testing I discovered that it was the DTS Connect features which were causing the problems you mention as well as (for some weird reason) random lockups. I eventually found that the "SoundMAX_Audio_v6106260" drivers (available from the Asus Website) fixed the issues although they don't include the DTS components. Oh well, at least it half works.

As well as the DTS issues I also read that Asus messed up the filters creating overly high output at some frequencies. Again, I think the drivers I mentioned above should help with this. You should be able to see if this is a problem for you as I think it only effected "processed" audio not bitstream.

Hope this helps.

Make sure you don't have the audio set to a resolution that it can't support. I had a Soundmax on a Asus board that I found through tons of tinkering that it only supported 44.1kHz.

This has been a nightmare! I can't seem to get digital output from the onboard optical out. It seem to only transmit sterio. I have the Cmedia 9880 sound chip with the latest drivers. I'm thinking of just purchasing a soundcard instead of using onboard audio. Any thoughts?
